Abstract
An apparatus includes a carrier, one or more first sensors, one or more second sensors, and one or more processors. The carrier includes a first frame and a second frame. A payload is affixed to the first frame. The second frame is rotatably coupled to a movable object. The one or more first sensors are disposed on the payload and configured to measure one or more motion characteristics of the payload. The one or more second sensors are disposed on the carrier and configured to measure one or more motion characteristics of the carrier. The one or more processors are configured to determine an input torque based on the one or more motion characteristics of the payload, determine an estimated disturbance torque based on the one or more motion characteristics of the carrier, and calculate an output torque based on the input torque and the estimated disturbance torque.
